help me with my sister and her partner

[uglybuglgly]

was vv close to my sister but she's been with a man fir 10 years and gradually he's marginalised me and my husband.
i haven't been with n her house this year
we share a holiday house and are there together now.
just her and me
her partner is coming out this weekend
i am dreading his arrival. i am immature and will find it difficult not to sulk in his presence.
i thought i'd talk ti my sister about the issues that have arisen but i can see she's taken the grey rock approach to all of it
he will arrive on thursday should i try and talk to her about the problem with our relationship or should i accept outr close relationship is over,
she seems to be pretty clear it's over but i feel very sad and angry about this .

No, don't accept. That's just what he wants. Get her onto Mumsnet relationships board ..
He sounds.. not good.

She might secretly be dreading his arrival also. You were once v close before he got in the way? Bad apple

My Sis husband is horrible. However as a grown adult, its her choice to be with him. He's not my husband, I neither have to live with or like him so I won't stress about it. I have my own partner and my own life to live.

The main thing is, your Sister is an adult and she's in a long-term relationship. You're also an adult, and need to take an adult view of this. Things don't tend to stay the same once we grow up, do they? You're not siblings in the same house anymore, you grow up and move on

Be there for her if she ever needs to talk. Maintain link with her as far as you can, talking about what has gone wrong between you is fine. But don't go on and on to her about her husband. Be mindful that she's already grey-rocking you so it seems to me she likes him, even if you don't. It's her life.
